Errors when Report is generated in C# with setup file

Dear Alok Sinha
        As of my understanding you may not passing the value to the parameter Length.  Please verify for while.  If your problem is not resolved please send me your code for a while i will try my level best to resolve this problem.
 

The most likely casue is that your program is getting an error that your program is ignoring so the programn continues executing until it gets a more serious error. You should look at all your source code and add code to check for errors wherever there is a possiblity for errors. Even if you modify your program in places that are not causing the problem, it is productive to have code to check for errors and that exits the program gracefully with a useful error message.
